In recent posts I’ve been dis­cuss­ing the changes in the use of EN 954 – 1, Safety of Machinery – Safety Related Parts of Con­trol Sys­tems. Part 1: Gen­er­al Prin­ciples for Design. The EU ori­gin­ally announced that this stand­ard was to be with­drawn on 31-Dec-09, being replaced by ENISO 13849 – 1. As you may know, there are sig­ni­fic­ant dif­fer­ences in these two stand­ards.

The EC has decided to extend the trans­ition peri­od for EN 954 – 1 from 31-Dec-09 to 31-Dec-12, delay­ing the man­dat­ory imple­ment­a­tion of ENISO 13849 – 1. How will this affect machine build­ers and con­trols man­u­fac­tur­ers?
